UNITED STATES GEORGES CLOETENS, OF ST. GILLES, NEAR BRUSSELS, BELGIUM.

REED ORGAN.

Application filed May 3,

To all whom 'it may coiwern.:

Be it known that I, GEORGES CLon'rENs, a subject of' the King of Belgium, and resident of St. Gilles, near Brussels, Belgium, have .invented certain new and useful Improvements in Reed Organs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked therein, which form a part of this specification.

The present invention relates to improvements in reed organs with beating reeds, and more particularly to improvements in reed organs with beating reeds of the kind described in my prior United States Patents No. 1,095,268 granted on 5, May, 1914, and No. 1,179,504, granted on 18, April, 1916.

The purpose of this invention is to improve upon the organs of the aforesaid patents in order to increase the artistic and musical possibilities of these types of organs and to permit a larger variation in the musical effects, and in the modification of the timbre or tone-quality.

In the reed organs, according to the above mentioned patents, I provide a plurality of beating reeds of different pitch forming a scale disposed along a resonating pipe; an air chest having one or a plurality of casings in communication with said reeds, valves between said reeds and said resonating pipe, controlling the selection of said reeds, and an auxiliary resonating pipe in communication with the prime resonating pipe; a tone slide disposed at the wider part of the prime pipe in order to permit the modification of the sound by controlling the outlet opening of said pipe, and an echo-bell, placed on 'foresaid part ot the resonating pipe.

The results directed by the present invention are obtained by the following features (1) In realizing the communication of the auxiliary resonating pipe, onv the side of the wider part of the prime resonating pipe not with this pipe but with the outer alr.

(2) In realizing the communication existing between the prime and the auxiliary resonating pipe by a plurality of openings of' substantially equal section.

(3) In ycontrolling the outlet of the air y 1922. Serial No. 558,053.

passing through these openings by the displacement of a suitable slide permitting to increase or decrease gradually the section of. said openings.

(4) In providing a valve or slide at the outlet opening towards the outer air of said auxiliary resonating pipe, in order to increase or decrease the section of said outlet opening.

In providing an echo-bell7 at the wider part of the auxiliary resonating pipe.

(6) In providing an auxiliary resona-ting pipe having a substantially conical form, the conicity being of the same direction as that of the prime resonating pipe.

(7) In providing a valve or slide similar to that specified under (4) on the side of the narrow part of the resonating pipes.

(8) In arranging the valves controlling the outlets of' the reeds in such a manner that the sound passing through said valves is directed by means of' the valves towards the auxiliary resonating pipe, in order to increase considerably the musical value off the sound.

' These and further features of the invention will now be described and claimed.

A preferred form of my invention is illustrated in the accompanying drawing, on which:

Fig. 1 is a transverse section through the resonating pipe of an organ embodying the invention.

Fig. 2 is a horizontal section on the line 2 2 of Fig. 1.

Fig. '3 is another horizontal section on the line 3-3 of Fig. 1.

Fig. 4 shows an element of the slide on a larger scale.

The type of' organ-stop shown atv the figures has an air chest l having one or a plurality of compartments 2, connected in the well-known manner (not shown) with the usual'wind or suction apparatus .not illustrated.- The reeds 3 are disposed along this air chest which communicateswith the resonator by means of the angled conduits il whose outlet openings are controlled by the valves, 5. These valves 5 may turn around their axis 6 and are pi voted by means of the keys 7 of the instrument a vregulating screw 9 being provided at the extremity 10 of each of said keys. A threaded bolt 11 increases or decreases the section of' each of the conduits 4. I

The resonator comprises aprirne rescinat.

ing pipe 12 ol' pyramidical torni, having a rectangular cross section as shown in Fig. 1, and of which the axis is parallel to that of the air chest 1, and an auxiliary resonating pipe 13 ot conical form, as shown in Fig. 1. rThe transverse sections of the two resonatinp,` pipes 12 and 13 taper in the same direction and on their outlet openings 14 and 15 are mounted echo-bells 16 and 1T ot lsuitable form, as shown in Fig. 3.

The prime pipe 12 communica-tes with the auxiliary pipe 13 by means oi' a plurality of openings 13 provided along` their adjacent lateral faces 19 andf20, these openings 1S having;Y a substantially equal section. A. slide 21 controlled by a suitable ineclianis1n\22, is provided with `openings 23, as shown in Fig.` a and can be displaced by translation between the adjacent 'laces 19 and ot' pipes 12 and 13. The openings 23 have preferably the substantially triangular torni shown in Fig. et and the alternate translation oi the slide 21 increases or decreases gradually the section. ot the passage of the sound towards the auxiliary pipe 13. The extreme positions ot tlieslide with respect to the openings 1S assure either the largest section or the narrowest oi? said openings.

At the outlets 14 and 15 of larger section ofthe. two resoiiating pipes 12 and 13 is provided a common ,tone-slide 26 to assure the crescendo or decrescendo effect of the instrument, said tone-slide beinecontrolled by a suitable mechanism 27. On another side, the passage ot these outlets 1st and 15 may be respectively obstructed by means of valves 28 and 29 pivoting around their axis 30 and 31. Similar valves 32 and 33 may be provided at the narrow outlets 34 and 35 of the pipes 12 and 13, as shown in Fig. 3, eac-h ot these valves 28, 29, 3e and 35 being controlled by a separate mechanism 36. 37, 38 and 39.

In respect to the perpendicular position ot the conduits 4: relatively to the openings 13, the angular displacement of the valves 5 realizes in the pipe 12 a directing plane, conducting` the sound towards the openings 18 abutting` in the auxiliary resonating pipe 13. v

The above described. improvements with the reeds mounted in the usual manner, enable ine to produce the purest notes by air at positive pressure or it operated by suction.

lt will be understood 4that a plurality of similar stops having varying' tone qualities may be combined in an organ as is characteristic of that instrument.
